Frequently Asked Questions
What receptacle does this plug mate with?
This plug requires a matching Bergstak receptacle with the same 0.8mm pitch and 40-position count. It does not mate with connectors of different pitches such as 0.5mm or 1.27mm. The receptacle part number determines the final mated stack height - verify against your design requirements before ordering.
Is this suitable for pick-and-place machine assembly?
These units are sold loose, not in tape-and-reel packaging. Suitable for manual placement, prototyping, or repair. Buyers requiring tape-and-reel for automated assembly should confirm packaging compatibility before purchase.
Is this part lead-free and RoHS compliant?
Yes. The LF suffix in the part number confirms lead-free, RoHS-compliant construction.
Can this be used with through-hole PCBs?
No. This is a surface-mount component and requires SMT soldering. It is not compatible with through-hole board designs.
The 54020-44030LF is an industrial SMT component. Confirm mating receptacle part number and stack height against your PCB layout before ordering.
